As a general rule, those parts which were bolted on after the basic engines were assembled and painted (in practice, blocks, heads, iron intake manifolds, iron exhaust manifolds, water pumps, crankshaft pulley, oil pans and bellhousings were all bolted in place and the engines painted as a unit) were semi-gloss black, pretty much the standard paint for Delco (starters, generators, coils) and AC (air cleaner, fan, power steering units and their respective pulleys).
